黄河流域水土保持规划主要技术指标论证 作者：王白春 刘红梅 许林军 摘要:规划主要技术指标的论证与确定是规划的重要技术环节。对黄河流域水土保持规划主要技术指标进行研究，旨在指导黄河流域水土保持规划的编制，使其规范化。在充分协商和论证的基础上，黄河流域水土保持规划(修编) 补充了黄河上游和下游的水土流失类型区，界定了全流域的水土流失面积，区分了上、中、下游和各省(区) 的水土流失面积，核实了现状治理面积，更新了现状水土保持减沙量，确定了新增治理和巩固提高治理面积，突出重点区域的治理措施和治理规模。 关键词: 水土保持; 规划; 技术指标; 黄河流域 中图分类号: S157;TV212．4;TV882．1 文献标志码:A doi:10．3969/j．issn．1000-1379．2013．10．043 Demonstration and Determination of the Main Technical Indicators of Soil and Water Conservation Planning of Yellow Ｒiver Basin WANG Bai-chun，LIU Hong-mei，XU Lin-jun Abstract: Demonstration and determination of the main technical indicators are of an important technical link of planning．The paper studied the main technical indicators of soil and water conservation planning of the Yellow Ｒiver for aiming at guiding the planning of the YellowＲiver water and soil conservation to make its standardization．On the basis of full consultation and demonstration，this plan (revision) replenished the water loss and soil erosion types of the Yellow Ｒiver’s upstream and downstream; defined soil erosion area of the whole basin; distinguished the water and soil loss area of the middle and lower reaches of the Yellow Ｒiver and the provinces (area); verified the status quo of management area; updated the present situation of sediment reduction through soil and water conservation; determined the new management and strengthened their management; highlighted the key areas of management measures and management scale． Key words: water and soil conservation; planning; technical indicators; the Yellow Ｒiver basin 自上一轮流域综合规划实施以来，黄河流域的水土流失状况和水土保持形势发生了重大变化。面对这些新情况和新挑战，要求水土保持规划要有新目标、新思路、新举措。 经过与各省(区)的多次协商讨论，在充分论证的基础上，《黄河流域水土保持规划(修编)》(以下简称本次规划) 对一些重要技术指标进行了修正、补充、更新和完善，补充了黄河上游和下游的水土流失类型区，界定了全流域的水土流失面积，区分了上中下游和各省(区)的水土流失面积，核实了现状治理面积，更新了现状水土保持减沙量，确定了新增治理和巩固提高治理面积。 1 规划中水土流失面积的含义与界定 水土流失面积是水土保持工作的对象，也是水土保持规划的基础。水土保持规划中的水土流失面积，有两个用途:一是针对水土流失面积，安排规划治理措施的面积;二是把水土流失面积作为一个本底值，衡量和计算水土保持的进度与成效。因此，确定科学的水土流失概念，界定合理的水土流失面积，是本次规划的首要任务。 从严格的科学角度和专业技术角度来说，水土流失面积应该是一个
